Description
Technical field
The utility model belongs to technical field of automobile, refers in particular to the stretcher of a kind of band stepping assembly.
Background technology
Stretcher is a kind of compare conventional accessory in motor car engine, the adjustment of time chain and correction are played most important effect by it, being acted on by time chain primarily of the plunger in stretcher, plunger has elasticity, it is possible to the elasticity of chain effectively compensated, but after the carrying out of plunger elastic force is regulated, elasticity can strengthen, and the correction of chain was understood tightly, affects the transmission effect of chain, long-time running also can increase the abrasion of chain, reduces work-ing life.
Summary of the invention
The purpose of this utility model is to provide a kind of stretcher that can effectively control to revise the band stepping assembly of intensity and distance.
The purpose of this utility model is achieved in that the stretcher of a kind of band stepping assembly, comprise main body and plunger, plunger is installed in main body, wherein, described plunger is hollow structure, inside is provided with return spring, it is provided with valve seat below described plunger, described valve seat is provided with check valve, described main body is provided with through hole, stepping bar it is provided with in described through hole, the body of rod of described stepping bar is provided with step-by-step toothed, described stepping bar side is provided with stop block, described stop block is perpendicular to described stepping bar, described stop block one end is provided with the stop tooth suitable with described step-by-step toothed, the other end is provided with fastening piece, it is provided with spring between described stop block and fastening piece, by the reactive force of spring, guarantee that stop block closely can engage with step-by-step toothed, the end of described stepping bar is provided with gear sheet, the end of described plunger is provided with limited step, described gear sheet acts on limited step, the length preventing plunger from extending is excessively long, to chain over-correction.
According to the stretcher of upper described a kind of band stepping assembly, wherein, described step-by-step toothed and stop tooth are all in reversed acanthoid, both is towards the opposite, and engage each other, it is ensured that stepping bar can only outwards extend, and cannot bounce back, improve sharpness of regulation, it is ensured that the gear sheet on stepping bar can limit the distance that plunger outward extends accurately.
According to the stretcher of upper described a kind of band stepping assembly, wherein, described check valve comprises steel ball and valve gap, and described steel ball is positioned on the valve port of valve seat, and described valve gap is covered on described steel ball.
According to the stretcher of upper described a kind of band stepping assembly, wherein, being provided with pressure release valve block in described plunger, described return spring one end acts on pressure release valve block, and the other end acts on the end face of valve gap.
The utility model gives prominence to compared to existing technology and useful technique effect is: by regulating the distance of stepping bar extension, effectively limit the extension length of plunger, reaching accurately control plunger, to the corrected range of chain and dynamics, makes chain normally operate stably, extends work-ing life.
