Variable-diameter stepless speed changer

Abstract

The invention discloses a variable-diameter stepless speed changer. The variable-diameter stepless speed changer comprises a driving wheel set, a driven wheel set and a speed changing belt (6). The driving wheel set comprises a driving wheel static disc (2), a driving wheel moving disc (3) and a driving wheel compression spring (4). The driving wheel static disc (2) is fixed to an output shaft (12). The driving wheel moving disc (3) is arranged on the output shaft (12). The driving wheel compression spring (4) ejects the driving wheel moving disc (3) to clamp the speed changing belt (6). The driven wheel set comprises a driven wheel static disc (8), a driven wheel moving disc (7) and a driven wheel compression spring (15). The driven wheel static disc (8) is fixed to an input shaft (16). The driven wheel moving disc (7) is arranged on the input shaft (16). The driven wheel compression spring (15) ejects the driven wheel moving disc (7) to clamp the speed changing belt (6). The elasticforce of the driven wheel compression spring (15) is much larger than that of the driving wheel compression spring (4). The variable-diameter stepless speed changer has the advantages of simplicity and reasonability in simple, convenience in operation and use, wide speed change range, good speed adjustment effect, stability, reliability, low production cost and the like.

Description

technical field [0001] The invention relates to the technical field of variable speed transmission, in particular to a variable-diameter continuously variable transmission for driving the rear wheels of a snowplow. Background technique [0002] Traditional snow removal methods mainly include artificial snow removal, chemical solvent snow removal and mechanical snow removal. Manual snow removal generally adopts the methods of pushing, shoveling, and sweeping. Its disadvantages are time-consuming, labor-intensive, low efficiency, and only suitable for small-area sites; although chemical solvent snow removal is simple and trouble-free, the snow-melting agent will chemically attack the road surface and shorten the service life of the road. At the same time, there is also the problem of serious pollution to the surrounding environment; mechanical snow removal is currently the most effective method of snow removal, not only the speed of snow removal is fast, the efficiency of snow...

Problems solved by technology

Manual snow removal generally adopts the methods of pushing, shoveling, and sweeping. Its disadvantages are time-consuming, labor-intensive, low efficiency, and only suitable for small-area sites; although chemical solvent snow removal is simple and trouble-free, the snow-melting agent will chemically attack the road surface and shorten the service life of the road. At the same time, there is also the problem of serious pollution to the surrounding environment; mechanical snow removal is currently the most effective method of snow removal, not only the speed of snow removal is fast, the efficiency of snow removal is high, and the cost of snow removal is low, and it will not cause environmental pollution. Therefore, all kinds of snow removal Small, fast and affordable snowplows emerged and quickly gained popularity

However, the current small snowplows have the following problems: the existing snowplows generally realize rear wheel speed regulation by adjusting the friction radius of the friction wheel and the friction disc, the friction wheel and the friction disc occupy a large space, and the speed change range is narrow. Easy to cause beating, poor stability, large size, high production cost

In response to the above problems, many manufacturers and people of insight have developed and developed, but so far no satisfactory products have come out.
