Hydraulic retarder transmission control mechanism

Abstract

The invention discloses a hydraulic retarder transmission control mechanism. The mechanism is characterized by comprising a planet gear mechanism, a brake and a transmission control mechanism shell; the planet gear mechanism is composed of a sun gear, a planet carrier, a disc-shaped gear ring and two or more than two planet gears; the brake comprises a brake disc and a brake part; and the sun gearserving as a retardance fixing end of the planet gear mechanism is fixedly connected with the brake disc, the disc-shaped gear ring serving as the retardance output end of the planet gear mechanism is in transmission connection with a retarder shaft, and the planet carrier serving as the retardance input end of the planet gear mechanism is in transmission connection with a transmission shaft of avehicle or / and a transmission output shaft. According to the mechanism, the problem that a transmission connection mode of an existing retarder affects vehicle power and economy is solved, and on thepremise that the transmission and the reliable work of the hydraulic retarder are guaranteed, the influence of the hydraulic retarder in the non-working state on the power performance and the economical efficiency of the vehicle is improved.

Description

technical field [0001] The invention belongs to a retarding braking system of a vehicle, in particular to a control mechanism for controlling the retarding braking force transmission of a hydraulic retarder. Background technique [0002] The driving vehicle uses the service brake to decelerate or stop, especially for road passenger and cargo transport vehicles with a large passenger capacity and a large cargo capacity, when encountering a long-distance downhill, the vehicle speed must be controlled by braking to ensure Driving safety. At present, mechanical friction brakes of various structures are mainly used on vehicles. Under long-term braking conditions, this type of brake will cause the temperature of the friction brake pair to rise due to friction, performance attenuation, and braking performance. Therefore, the auxiliary braking system and the mechanical braking system on the vehicle can effectively improve the braking effect, reduce or avoid the failure of the mecha...
