Problems solved by technology

This increases the complexity of the control of the shifting device. It takes a long time to achieve synchronization between the shaft and the gear through friction, resulting in a small discontinuity in the speed during shifting, and the energy of the speed difference during the shifting process is dissipated in the form of heat energy.

Abstract

The invention relates to the field of vehicle engineering, in particular to a multibuffer-harpoon-shift device which is arranged on a transmission shaft with a gear. The multibuffer-harpoon-shift device comprises joint parts, guide sleeve assemblies and an joint sleeve, and flexible buffering connection units, wherein each guide sleeve assembly comprises a plurality of guide sleeves which are arrayed in the axial direction; the flexible buffering connection units are used for transmitting peripheral power between the joint parts and the guide sleeves; each joint part is provided with an inserting groove; inserting teeth are arranged on the joint sleeve; each guide sleeve comprises a guide block and a guide hole; when the flexible buffering connection units are at a natural extension state, the adjacent two guide sleeves are mutually staggered along the peripheral direction; the inserting grooves and the corresponding inserting teeth are separated by the guide blocks. The multibuffer-harpoon-shift device provided by the invention does not need a hydraulic control system and has the advantages of simple structure, small weight, rapid reaction speed, small shifting impact and a smoother shifting process; the occluded tooth quantity also can be reduced.

Description

technical field [0001] The present application relates to the field of vehicle engineering, in particular to a multi-layer cushioning insertion engagement type shifting device. Background technique [0002] The gearbox expands the range of torque and rotational speed of the power source by changing the transmission ratio, makes the power source work under high power conditions under different operating conditions, and reverses the equipment when the rotation direction of the power source remains unchanged run, and interrupt power transmission through neutral selection without interrupting the power source. [0003] In the related art, the gear shifting device widely uses a synchronizer to realize gear shifting. The synchronizing effect of the synchronizer is based on the friction force of the conical friction surface between the ring gear and the synchronizing ring. In order to achieve sufficient friction, the shifting device is usually equipped with a hydraulic control sy...
