专利汇可以提供Brake operated transmission neutralizer专利检索，专利查询，专利分析的服务。并且A vehicle which has a transmission having forward and reverse control means in which the forward and reverse control means is connected to a bracket member on the manual control lever to shift the transmission from neutral to forward or reverse; the vehicle is further equipped with a brake mechanism actuated by a pivoted brake pedal which is connected by means of a return spring to the bracket member attached to the control lever; the spring normally tends to constantly urge the control lever in the neutral position; when in tension a lost motion connection is provided between the spring and the bracket member to allow the bracket member to be pivoted by shifting of the direction control lever without loading the spring; the mechanism functions such that, when the brake is applied, the lost motion connection is taken up and the spring is tensioned causing the direction control lever to return to neutral; the spring and the bracket member on the control lever further provides an override means permitting the tractor transmission to be shifted into forward or reverse before the brake is released by stretching the spring to obtain vehicle motion prior to complete brake release.，下面是Brake operated transmission neutralizer专利的具体信息内容。

权利要求

1. In combination with a vehicle having a prime mover and traction wheels including brakes and a transmission operably connected between said prime mover and said traction wheels; a brake actuating mechanism connected to the brakes of said traction wheels and a manually operable direction selector control lever for said transmission pivotally mounted on said vehicle fOr movement between a forward and reverse drive position from a central neutral position; the improvement comprising: a pivot member mounted on said control lever for pivotal movement therewith; a link pivotally mounted on said pivot member and operably connected to said transmission for placement of said transmission in the respective drive position, corresponding to the selective position of said control lever; said brake mechanism including a brake rod connected to said brakes at said traction wheels and to a brake pedal; tension means connected between said brake pedal and said pivot member to normally retain said brake pedal in an inoperative position and normally disposed along an axis incidental with the neutral position of said control lever; and means permitting displacement of said tension means from said axis towards both sides thereof upon shifting of said control lever to the forward or reverse drive position without tensioning said tension means, whereby said tension means is operable to return to said axis incidental with the neutral position of said control lever when said tension means is tensioned by depression of said brake pedal while said control lever is in a selected drive position.

2. In the combination as defined in claim 1, said means permitting displacement of said tension means from said axis comprising a lost-motion connection.

3. In the combination as defined in claim 2, said control lever having a pivot shaft mounted for pivotal movement around an axis in said vehicle, and said pivot member comprising a bracket secured to said pivot shaft, said link being mounted on said bracket to one side of said pivot shaft and said tension means being mounted on said bracket forwardly of said pivot shaft along an axis normally intersecting the axis of said pivot shaft.

4. In the combination as defined in claim 3, said lost-motion connection comprising a slot in said bracket and the end of said tension means connected to said bracket being normally disposed in the rear end of said slot when said control lever is in a neutral position and the brake pedal is in inoperative position to thereby permit pivotal movement of said bracket with said pivot shaft when said control lever is shifted to a selective drive position without tensioning of said tension means.

5. In the combination as defined in claim 4, said tensioning means comprising a coil spring.

6. In a return-to-neutral control mechanism for use in a vehicle having a transmission and a brake actuating mechanism, said control mechanism comprising: a control lever having a shaft rotatably mounted in said vehicle for pivotal movement of said control lever around an axis between a first and a second drive position from a neutral central position; said pivot shaft having a bracket member mounted thereon for rotation therewith; a first linkage means connecting said bracket member with said transmission; said brake actuating mechanism comprising a brake rod operably connected to a brake pedal; elongatable second linkage means connecting said brake pedal with said bracket member and normally disposed along an axis intersecting the axis of said shaft when said control lever is in said neutral position; means comprising a lost-motion connection between said elongatable second linkage means and said bracket member to permit pivotal movement of said bracket member without elongating said second linkage means and displacing said axis from the intersecting position with said shaft axis; said lost-motion connection being taken up when said brake pedal is depressed to thereby elongate said second linkage means and return said control lever by means of connection to said bracket member to the neutral position from a selective drive position and into aligned intersecting position with said shaft axis.

7. In the control mechanism as defined in claim 6, said bracket member in cooperating relationship with said second linkage means and said lost-motion connection providing an override means to permit shiftinG of said control lever into a selective drive position when said brake pedal is depressed prior to release of said brake pedal.

8. In the control mechanism as defined in claim 7, said lost-motion connection comprising a slot in said bracket member and said second elongatable linkage means comprising an energy storing tension member having one end slidingly disposed in said slot normally in the rear end thereof when said control lever is in neutral and said brake pedal is in inoperative position; said one end being adapted to be displaced in said slot towards the front end thereof upon pivotal movement of said bracket member by shifting of said control lever in either first of second drive position to thereby permit loading of said energy storing tension member unless the brake pedal is depressed.

9. In the control mechanism as defined in claim 8, said energy storing tension member comprising a coil spring.
