Embodiment Construction

[0017] see figure 1 , the transmission brake based on the clutch actuator of the present invention includes a clutch release bearing 1, a brake bracket 2, a brake piston 3, a brake friction plate 4, a brake steel plate 5, a spring sleeve 6 and a compression spring 7; Piston 3, brake friction plate 4, brake steel plate 5 constitute braking device, and braking device is installed on two intermediate shaft shaft heads. The brake friction plate 4 and the brake steel plate 5 form a friction pair.

[0018] The way of the brake bracket 2 may not be limited to this mechanical structure, and electronic sensing and hydraulic drive or electromagnetic drive may also be used, as long as the drive of the clutch release bearing to the brake piston is realized. The friction pair can also be in the form of a friction cone, that is, the braking is completed through the adaptation of the piston cone to the cone on the intermediate shaft. The brake friction lining 4 is a non-metal material, and...

Abstract

The invention discloses a transmission brake based on a clutch actuating mechanism, wherein the transmission brake comprises a clutch separation bearing, a sensing driving device and a brake device, wherein the sensing driving device is connected with the clutch separation bearing; the brake device is arranged between transmission intermediate shafts and a transmission shell; and the sensing driving device is adaptive to the brake device. According to the transmission brake based on the clutch actuating mechanism, friction devices are installed on the shaft heads of two intermediate shafts; and the brake response is rapid, and the transmission brake based on the clutch actuating mechanism is stable and is high in intensity.

Description

technical field [0001] The invention relates to the field of vehicle transmissions, in particular to a transmission brake based on a clutch actuator. Background technique [0002] At present, a brake is included in the AMT system of commercial vehicles at home and abroad. The brake is used to brake and decelerate a shaft and its associated transmission components when the vehicle starts and upshifts, so as to shorten the synchronization time and reduce the impact of shifting. The brakes for AMT are installed in the power take-off window of the transmission or at the shaft head of the intermediate shaft according to different designs. The driving forms mainly include electromagnetic, hydraulic and pneumatic. These three types of brakes require special actuators to drive, and each has advantages and disadvantages. The electromagnetic brake responds quickly, but the structure is complex. Hydraulic and air brakes are slow to respond, and there are problems with oil and gas l...
