Abstract

The invention belongs to the automotive transmission field, in particular to a shock absorption input shaft assembly. The shock absorption input shaft assembly comprises an input shaft, an input gear, a gear pressing plate and a spring pressing sheet, wherein the input gear and the gear pressing plate are assembled on the input shaft through rigging pins, the input gear and the input shaft transmit torque through a torsion spring, and the input shaft adjusts the change of the torque transmitted from the input gear through the deformation amount of the torsion spring to realize stability and alleviation of input. According to the shock absorption input shaft assembly, a shock absorption device is additionally arranged on the input shaft of a transmission, the instability of the rotating speed of the input shaft is eliminated through the shock absorption device in the running process of the input gear, sufficient buffering is realized, and the purpose of removing idling noise and other problems caused by unstable output of an engine is achieved.

Description

A kind of shock-decreasing type input shaft assembly

Technical field

The invention belongs to the automotive transmission class, specifically a kind of shock-decreasing type input shaft assembly.

Background technique

What now the most domestic commercial car adopted is generally four-stroke ic engine, and four-stroke ic engine easily causes torsional vibration because of itself periodic motion, adds the sequentially fired of casing top half, the irreqularity of having brought bent axle to rotate.and the feature natural frequency that power transmission system has, can be converted into the torsional vibration transmission to the irregular rotation that motor produces to speed changer again, and speed changer is because of its reasons in structure, must be gapped during the gear engagement, irregular input, caused the not steady of gear engagement, the problems such as idling abnormal sound of speed changer have been caused, have a strong impact on the performance of speed changer, the improvement project of present most of auto vendor is for to improve in clutch part, as increase double mass flywheel and implement secondary damping scheme, but each large speed changer producer does not all have and can carry out substantial improvement design for this structure itself.

Summary of the invention

The objective of the invention is for the deficiencies in the prior art, a kind of shock-decreasing type input shaft assembly is provided, it increases damping device from the input end of speed changer own, thereby slows down or eliminate due to the not steady series of problems such as idling noise that bring of motor output.

The present invention is achieved by the following technical solutions:

The present invention is a kind of shock-decreasing type input shaft assembly, comprise input shaft, input gear, gear pressing plate, spring pressuring plate, input gear and gear pressing plate are assemblied on input shaft by rigging pilotage, input gear and input shaft are by the torsion spring transmitting torque, input shaft is regulated the variation of input gear transmitting torque by the amount of deformation of torsion spring, reach the steady mitigation of input.When motor outputs to driven disc, driven disc transmits torque to input shaft, input shaft passes through torsion spring, after torsion spring is pressed and being out of shape one section, after reaching Spring balanced, transmit torque to input gear, thereby complete the speed changer transmission, torsion spring changes along with the regular movements of motor input thereupon, and the rotating speed and the moment of torsion that guarantee to be input to speed changer inside are steady, solve because of the not steady series of problems that is brought of motor output with this.

The present invention is by increasing damping device on transmission input shaft, eliminate the not stationarity of input speed by damping device in the gear operation process, from the jiggly problem of speed changer input solution motor output, abundant buffering reaches and eliminates idling noise etc. due to the purpose of the not steady series of problems that brings of motor output.

Description of drawings

Fig. 1 is embodiment of the present invention structural representation.

Fig. 2 is the right elevation of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the present invention being done one specifically describes;

as Fig. 1, shown in 2, a kind of shock-decreasing type input shaft assembly, by input gear 1, gear pressing plate 2, rigging pilotage 3, input shaft 4, spring bearer plate 5, spring bearer plate pin 6, torsion spring 7 forms, input gear 1 and gear pressing plate 2 are assemblied on input shaft 4 by rigging pilotage 3, spring bearer plate 5 use spring bearer plate pins 6 are fixing, both sides guarantee that torsion spring 7 is on input gear 1 and input shaft 4, input gear 1 and input shaft 4 are by torsion spring 7 transmitting torques, work as engine output torque, spline transmitting torque by input shaft 4 front portions, input shaft 4 concerns rotary compression torsion spring 7 because of moment of torsion, after the elastic force of torsion spring 7 and moment of torsion are reached balance, transmit torque on input gear 1, when engine output torque or the unexpected irregular variation of rotating speed generation, because its moment of torsion and rotating speed that is delivered on input shaft 4 changes, cause torsion spring 7 to need rebalancing, make moment of torsion and the rotation speed change of input gear 1 tend towards stability, thereby reach the purpose that the speed changer smoothing input relaxes.

Claims

1. shock-decreasing type input shaft assembly, comprise input shaft, input gear, gear pressing plate, spring bearer plate sheet, it is characterized in that: input gear and gear pressing plate are assemblied on input shaft by rigging pilotage, input gear and input shaft are by the torsion spring transmitting torque, and input shaft is regulated the variation of input gear transmitting torque by the amount of deformation of torsion spring.
