Problems solved by technology

However, some drivers often do not step on the clutch pedal to engage or remove gears during driving, resulting in excessive synchronizing torque of the synchronizer, causing high temperature, causing damage to the synchronizer, and seriously reducing the service life of the synchronizer in the gearbox. will affect driving safety
[0004] During normal driving, if encountering strong bumpy roads, etc., the transmission will have the risk of gear loss caused by factors such as the vehicle manipulator and lever system shaking. If gear loss occurs, it will also cause the synchronization of the transmission damaged severely

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0034] see figure 1 , is a traditional gear shifting device, the control housing 2 is equipped with a shift joint 1, and the shift joint 1 rotates axially under the action of an external force to realize the gear shifting of the gearbox 12.

[0035] The mechanical gearbox synchronizer protection system of the present invention includes a shifting device, a pressure supply pipeline, a pipeline on-off control valve and a pressure supply source; see figure 2 , is the shifting device of the present invention, including a shifting joint 1, a shifting operation housing 2, a cover plate 6, a locking structure and a spring 8.

[0036] A shift connector 1 is arranged inside the shift operation housing 2, and a first groove is arranged on the shift connector 1; a through hole is provided on the part ...

Abstract

The invention provides a protection system and a method of a mechanical gearbox synchronizer. A gear locking mechanism is additionally arranged on a gearbox shifting device; when a clutch is not thoroughly separated or the clutch is not separated, the gearbox shifting device is locked by the gear locking mechanism, and gear shift cannot be implemented; and after the clutch is separated, the gear locking mechanism is unlocked, and at the moment, a driver can shift, so that the synchronizer is prevented from being damaged by gear shift when the clutch is not separated. According to the protection system and the method, the gear shift habit of the driver can be specified, the driver cannot shift in the condition that the clutch is not trodden, and the synchronizer is prevented from being damaged in advance due to violation operation; the off-shift hidden danger of a gearbox can be avoided when driving on special roads such as big bump and the like, so that the driving safety is greatly increased. According to the protection system and the method, the service life of the synchronizer can be prolonged, so that the service life of the gearbox is prolonged.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, in particular to a mechanical gearbox synchronizer protection system and method. Background technique [0002] Damaged mechanical transmission main case synchronizers are consistently among the top 10 aftermarket failures. One of the main reasons is that the driver's clutch is not completely disengaged or the clutch is not disengaged during the shift operation, resulting in damage to the synchronizer. [0003] During the shifting operation, there is a speed difference between the first shaft and the second shaft of the gearbox. After the power of the engine must be cut off from the first shaft through the clutch, the synchronizer in the shifting operation can rely on friction well. Synchronize the speed of the first shaft with the second shaft to realize gear shifting. However, some drivers often do not step on the clutch pedal to engage or remove gears during driving, resulting in excessive ...
