Problems solved by technology

[0004] Although the above-mentioned single motor preliminarily solves the problem of space allocation and cost caused by the installation of dual motors in the gearbox, the motor must have two different directions of forward rotation and reverse rotation to complete a gear change. There will be delays and frustration
[0005] And the rocker arm uses the power of the pawl return spring to link the clutch cam, which will lead to poor linearity of the clutch cam, and the transmission through the rocker arm will also make the accumulative accuracy from the motor to the clutch cam worse
[0006] Moreover, the driven system of the gearshift drum is promoted by the ratchet, and it must be pushed back to the original position by the spring before it can be driven again. Restricted on consecutive gears

[0024] see figure 1 , the vehicle gear mechanism of the present invention is used to drive the clutch actuation of the clutch 2 of the gearbox 1 and the gear change of the gear drum 4. The clutch 2 also has clutch actuators 21 and 22 for actuating the clutch. The present invention The vehicle gear mechanism can include: a camshaft 31, linked to the gear drum 4; an actuating motor 3, driving the camshaft 31, so that the camshaft 31 rotates one revolution and simultaneously makes the gear drum 4 change a gear position; and a cam 32 , is connected to the camshaft 31 and rotates coaxially with it and is used to press the clutch actuator 21 of the clutch 2, and then the clutch actuator 21 presses the release of the clutch 2 arranged above the clutch actuator 21 The bearing actuator 22 and the clutch release bearing 26 arranged on the release bearing actuator 22 enable the clutch 2 to carry out clutch operation. The cam 32 can have a symmetrical profile, so that the camshaft 31 can ...

[0033] see image 3 , the present embodiment is substantially the same as the first embodiment, except that the camshaft 31 can be provided with a balance cam 33 coaxially rotating with the cam 32, and the balance cam 33 and the cam 32 have contours mutually and the balance cam 33 can be used to abut against an elastic device 34 connected to the casing of the gearbox 1 to obtain elastic support. The spring 341 in 340, the support seat 342 located at the end of the spring 341, the roller 343 that is axially connected to the support seat 342 and is in rolling contact with the balance cam 33, the circumference of the support seat 342 can be coated with a guide The housing 344, whereby the support seat 342 can only perform reciprocating linear motion, and then elastically supports the balance cam 33, so that the balance cam 33 can be used to counteract the effect of the cam 32 on the cam when the camshaft 31 rotates. Most of the moments of the shaft 31 are used to avoid damage ca...

Abstract

A speed mechanism used for vehicles is used for driving the clutch movement of a clutch in a transmission case and the shift conversion of a speed drum. The speed mechanism used for vehicles comprises a camshaft, an actuating motor and a cam; wherein, the camshaft is interlocked with the speed drum; the actuating motor actuates the camshaft to turn for a circle and simultaneously causes the speed drum to transform a speed; the cam is connected with the camshaft, turns on the same axis with the camshaft, and is used for pushing against a release actuating piece of the clutch so as to actuate the release and jointing of the clutch. The cam is provided with the symmetrical outline and causes the camshaft to turn for a circle for the same direction by the actuating motor, and simultaneously, realizes the actuating of the clutch and the transformation of the speed of the speed drum.

Description

technical field [0001] The present invention relates to a gearshift mechanism for a vehicle, and more specifically relates to a gearshift mechanism for a vehicle which integrates the power source of the actuation of the clutch in the gearbox and the shifting of the gear position of the gearshift drum into the same actuating motor. Background technique [0002] As far as vehicles with automatic manual transmission (AMT) mechanisms are concerned today, the principle of gear shifting is that the automatic clutch actuator in the gearbox controls the engagement or disengagement of the clutch, and the automatic gear actuator controls the rotation of the gear drum to perform gear. The clutch and the gear drum each have a set of actuators and motors to propel them. However, the use of at least two sets of actuators and motors in the AMT mechanism will not only be greatly restricted in terms of space configuration, but also set up two sets of actuators and motors. Additional actuato...
