Abstract
The utility model provides a floating caliper body disk type brake for electric vehicles. A brake caliper comprises a brake disc, a brake caliper body, and a brake block; a friction block can be replaced at any time; friction gaps can be automatically compensated. The utility model has the advantages of simple and convenient repair, time saving, light weight, low cost, and sensitive and safe brake, and is particularly suitable for two-ton electric vehicles.
Description
The utility model is the braking device about the electronic transport vehicle in place.
Electronic transport vehicle is commonly called as storage battery car, and little, convenient, flexible, the no exhaust emission pollution of volume is particularly suitable for the place transportation.The electronic transport vehicle of the present electronic transport vehicle that uses, particularly two tons of load-carryings because braking ability is bad, often crashes, and causes the car body profile incomplete.The present mechanical brake that generally uses, when flat road surface and the speed of a motor vehicle are slow, braking effect still can, and when full load meets ramp or urgency, can not bring to a halt, the vehicle of having to take to advance becomes immediately and retreats, and causes part premature damage such as differential mechanism, gear.Current have a kind of hydraulic drum brake, though braking ability is better, and its improvement expenses costliness, the expense of only buying break just approaches to buy the price of a new storage battery car, is difficult to promote.Excesssive gap between this break brake shoe and the brake drum or too smallly all can influence braking effect just need often be adjusted for keeping certain clearance, as adjust the improper braking skew that then can produce in addition, and reduction retardation efficiency etc. make troubles to operation.The friction heat radiation produces the heat fade phenomenon slowly between moving hoof of this break work schedule and the brake drum.
Purpose of design of the present utility model is to provide a kind of sensitivity, safe and reliable and break that operation and maintenance is easy braked for electronic transport vehicle, guarantee in the brake pad length of life, its wearing and tearing can compensate automatically, from adjust the play, thereby improve the usability of break.
Accompanying drawings technological points of the present utility model:
Accompanying drawing 1 is the unsteady caliper disk type braker structure principle chart of electronic transport vehicle, and Fig. 2 is a brake slipper end surface shape structural drawing.
Wherein: 1,1 '-braking clamp body 2-filler opening
3-hydraulic jack 4-piston
Anechoic sheet in the 5-seal ring 6-
6 '-outer anechoic sheet 7-entodorsum
7 '-the interior brake pad of outer backboard 8-
8 '-external friction piece 9-brake disc
The outer brake slipper 10 of 10-'-the inside brake piece
11-wheel axle 12-back-up ring
13-claw type spring
The electronic transport vehicle caliper disk type braker that floats, by braking clamp body (1) (1 ') with its in form brake caliper assy altogether for the brake slipper (10) (10 ') and the brake disc (9) of two symmetries of interior piston (4) of the hydraulic jack of tubular (3), cylinder and attaching.Brake calipers is contained on the wheel axle by four rubber bushings, steel pilot pin and receiving and conversion equipment are floating.Braking clamp body external part (1 ') and piston (4) bottom attaching respectively outer brake slipper (10) and inside brake piece (10 ') and is clamp-shaped and constitutes in the middle of symmetrically brake disc (9) being clamped in and brake, the end face of brake slipper (10) (10 ') is fan-shaped, be made up of outstanding respectively being contained on entodorsum (7) and the outer backboard (7 ') of interior brake pad (8), external friction piece (8 '), brake pad (8) (8 ') is to be formed by the copper wire material used heating and mould pressing of asbestos.The noise that is anechoic sheet (6) (6 ') and packing ring outside the inside and outside backboard, produces when anechoic sheet can alleviate braking.Brake disc (9) is the metal matter dish with the circle of the rotation of end face work, the front wheel brake dish by bearing fixing on wheel shaft, the trailing wheel brake disc is fixed on the rear vehicle shaft of band gradient by semiaxis pin and nut, on hydraulic jack (3) inwall in the braking clamp body (1) the trapezoid cross section annular groove is arranged, embed the rubber seal (5) of rectangular cross-section in the annular groove, there is pit on piston (4) top in the hydraulic jack (3), embedding rubber back-up ring (12) in the corresponding rectangle annular groove of rectangle annular groove and oil cylinder (3) inwall bottom is arranged at its bottom, have claw type spring (13) to prop up in piston (4) bottom and adorning inside brake piece (10 '), braking clamp body (1) and piston (4) all can be steel material.During braking, give braking overall pump by brake petal, lever transmission, hydraulic oil is pressed into hydraulic jack (3) by filler opening (2), under hydraulic pressure, promote piston (4) and push against on the brake disc (9) together with inside brake piece (10 '), braking clamp body (1) (1 ') is along the wheel axle slippage simultaneously, come on the outer brake slipper (10), hydraulic pressure continuation effect, because pressure and counter-force effect, inside brake piece (10 ') and outer brake slipper (10) clamp brake disc (9) simultaneously and reach braking.During brake off, hydraulic pressure is removed, and piston (4) is worth in rubber seal (5) elastic force effect next time together with inside brake piece (10 ') and interior anechoic sheet (6) and packing ring, till seal ring (5) distortion complete obiteration.Gap (also being brake clearance) between brake pad (8) (8 ') and the brake disc (9) is a setting value at this moment.If break produces excessive gaps because brake pad weares and teares, promptly the gap becomes big, and after the seal ring distortion reaches capacity during braking, then piston (4) will overcome the frictional force continuation slippage of seal ring, till brake pad (8) (8 ') clamps brake disc (9).Seal ring (5) makes piston return and regulating brake gap effect automatically simultaneously except sealing, realize clearance automatic compensation whereby.
Outstanding advantage of the present utility model is that braking is sensitive, safe and reliable, braking ability gentle, stablizes, and is four-wheel braking, and braking direction is steady.Because brake disc is exposed at rapid heat dissipation in the atmosphere outward, has reduced heat fade, braking effect is stable, does not have friction and helps the gesture effect.The immersion back only needs slight several times friction catch can recover the normal brake application effect.In light weight, the low price of the utility model can reach safety in production, can be enterprise and saves transformation funds and causality loss expense.This brake structural is simple, and operation and maintenance is convenient, saves time.Brake pad is a standard piece, can change at any time.The wearing clearance of brake pad can compensate automatically, need not artificial often adjustment.
Embodiment: the unsteady caliper disk type braker of electronic transport vehicle has been applied on two tons of electronic transport vehicles of load-carrying, reaches requirement fully through practical its braking ability.
