Embodiment Construction

[0017] The pneumatic transmission brake proposed by the present invention includes a shaft 1, a gasket 2, a bearing 3, a baffle plate 4, a spring 5, a gear 6, a ball bearing 7, a cylindrical pin 8, a housing 9, a spline shaft 10, and a steel sheet 11 , Friction plate 12, piston 13, cylinder 14, gas circuit 15. The piston 13 reciprocates along the shaft 1 in the cylinder 14, the spline shaft 10 is nested on the shaft 1, the spring (5) is arranged between the piston 13 and the spline shaft 10; the air passage 15 is arranged at the end of the shaft 1, It is connected with the piston 13 and the cylinder 14.

[0018] Steel sheet 11, friction plate 12 all are many, and number can be adjusted and installed as required, to adapt to different braking requirements. The steel sheet 11 and the friction sheet 12 are adapted to each other; the steel sheet 11 and the friction sheet 12 are divided into two groups, which are arranged on both sides of the spline shaft 10 respectively. The bra...

Abstract

The invention provides a pneumatic speed changer brake, which comprises a shaft, a spring, a gear, a spline shaft, a steel sheet, a friction plate, a piston, a cylinder and an air path. The piston which does reciprocating motion along the shaft and the spline shaft sleeved on the shaft are arranged in the cylinder; the spring is arranged between the piston and the spline shaft; the steel sheet and the friction plate are arranged on the two sides of the spline shaft; the steel sheet is connected with the gear through the spline shaft; the friction plate is connected with the spline shaft through a spline; and the air path is arranged at the end of the shaft and connected with the piston and the cylinder. When the speed changer is shifted up, the brake can quickly reduce the rotation speed of the shaft and related parts of the speed changer, shorten the synchronization time and improve the gear shift performance.

Description

technical field [0001] The invention relates to a transmission braking device, in particular to a pneumatic transmission brake. Background technique [0002] With the rapid development of the national economy, people have higher and higher requirements for the driving comfort of automobiles. The transmission, which is an important part of the automobile power train, mainly refers to the quality of shifting, that is, smooth shifting and short power interruption time. [0003] At present, the domestic research on the transmission brake has just started, and the transmission brake installed at the power take-off window is still blank. Foreign transmission brakes have complex structures, troublesome maintenance and installation, and poor versatility. Therefore, there is a need for a brake that can decelerate a transmission shaft and its associated parts when the transmission is upshifted, so that the parts that need to be synchronized when shifting gears are quickly synchroniz...
