Abstract
The present invention relates to an axle braking device for vehicles. The present invention has a main structure that both ends of a vehicle axle are respectively provided with a left axle block and a right axle block, wherein a cam surface is machined on the left axle block, and a rolling body is arranged between the cam surface and a brake rim; teeth are machined on one end of the right axle block, and ratchet pawls engaged with the teeth are arranged in the grooves of an axle bowl; both ends of a flower-drum cylinder are respectively connected with the axle bowl and the brake rim. The axle braking device can be used on a bicycle or other vehicles; when a fly wheel rotates, the right axle block is driven, and wheels advance by the teeth on the right axle block engaged with the ratchet pawls on the axle bowl; when braking is carried out, a handle is pinched, a holding frame of the rolling body drives the rolling body to rotate together, and friction force and extruding force are generated between the rolling body and the brake rim to make the wheels carry out speed reduction or stop.
Description
The wheel hub that has brake equipment
The present invention is a kind of wheel hub that is used for vehicle, especially for the wheel hub of bicycle.
In the prior art, a kind of backpedalling brake and structural similitude of the present invention are arranged.The principal character of this backpedalling brake is: the driving of wheel together and the device of brake action are housed on vehicle.One end of vehicle is equipped with flywheel, and when flywheel clockwise rotated, running part drove wheel in this device, and car is advanced, and when flywheel rotated counterclockwise, brake portion slowed down car or stops in this device.The general structure of this backpedalling brake is complicated.The clear 56-33277(of Japanese Patent speciallys permit out hope bulletin) in introduced the better simply backpedalling brake of a kind of structure.In this piece patent, two kinds of schemes are arranged, a kind of is the cam that is processed with two different sizes on right axle bumper.Being contained in two scroll kinetoplasts on two cams plays drive wheels respectively and advances and brake.Be processed with saw shape tooth on the shell that another kind of scheme is a brake, a cam and a half slot are arranged on the right axle bumper.Be contained in the saw shape tooth engagement of driving pawl in the circular groove and shell inboard, drive wheel and advance.Rotating cam, rolling body promotes ringfeder, ringfeder and shell friction, brake wheel.In first kind of structure,, therefore the relative positional accuracy of two cams is had relatively high expectations because the lift of cam directly influences the driving and the braking effect of wheel.When driving, two kinds of motion converters of braking, the idle running of the centre section of having time flywheel.In addition, in two kinds of schemes, braking force, propulsive effort all act on an end of right axle bumper, and support end moment is bigger, and therefore right axle bumper is easy to generate distortion.During brake, ringfeder and wheel hub friction are easy to generate the iron end.The car of backpedalling brake is housed, uses inconvenience.Will be when getting on the bus with the foot-operated the place ahead or the below of moving on the left side.
Task of the present invention is the better simply wheel hub that has brake equipment of a kind of structure of design on the basis of backpedalling brake.
The objective of the invention is to realize by following measure.
Two ends at axletree are installed driver train and stop mechanism respectively, and two parts are connected by wheel hub.
At left end, the axle bowl, left axle bumper, nut is installed successively, between axle bowl and the left axle bumper and between left axle bumper and the nut one group of rolling body is housed respectively.One end of left side axle bumper is equipped with flywheel, and the other end is processed with tooth.In the groove of axle bowl, ratchet is housed, ratchet and above-mentioned tooth engagement.During driving, flywheel is just changeing the left axle bumper of drive and by this ratchet device wheel hub is being rotated.During counter-rotating, because institute's unidirectional transmission of the ratchet device that adopts, so flywheel dallies.
At right-hand member, installation shaft lock shell rolling body (two groups) successively, retainer and spanner and adapter plate, the periphery of right axle bumper is processed into cam, and the lift of cam should guarantee to make the certain positive pressure of generation between rolling body and the shell.A retainer end is in the outer part installed wrench, and it is moving thereupon to promote rolling body when wrench rotates counterclockwise.The lift of cam compresses shell with rolling body jack-up, reaches the purpose of brake.After unclamping the brake handle, be contained in the spring pulling retainer between wrench and the adapter plate, rolling body is resetted.
Described embodiment explains details of the present invention below in conjunction with accompanying drawing of the present invention.
The semi-section view of Fig. 1 axle lock car.
The A-A section-drawing of Fig. 2 Fig. 1.When left axle bumper conter clockwise changeed among the figure, wheel advanced.
The B-B section-drawing of Fig. 3 Fig. 1.When wheel advanced, axle lock shell (7) cw changeed.Glancing impact, retainer (3) cw changes.
As shown in Figure 1, right axle bumper (2), left axle bumper (12) is contained in the left and right sides of axletree (1) respectively.The inside and outside both sides of left side axle bumper have a circular groove respectively, and rolling body (13,11) is contained in respectively in two circular grooves, and left axle bumper is bearing on the axletree, and axle bowl (10) is bearing on the left axle bumper.One end of left side axle bumper is equipped with flywheel (14), and the other end is processed with tooth, this tooth and ratchet (15) engagement that is contained in the axle bowl.One end of ratchet has a round end, and round end is contained in axle bowl one end and the half slot that it matches.There is a spring (16) supporting at the middle part of ratchet, makes ratchet and tooth keep engagement.Right axle bumper one end is processed into cam, and the other end has circular groove.Rolling body (8,6) is housed respectively between cam, circular groove and the shell (7).Rolling body on the cam has a retainer (3), and rolling body (6) is placed in the open slot or slotted eye of retainer.One end of retainer is a polygon tenon, and spanner (5) cooperates with this tenon.The two ends of retracing spring are contained in respectively in the hole (17,18) of spanner and adapter plate (4).
When flywheel rotates counterclockwise, drive left axle bumper,, wheel hub (9) is rotated, thereby wheel is advanced by tooth on the left axle bumper and the ratchet engaged transmission that is contained on the axle bowl.Glancing impact, the pinching brake lever by pull bar or cable wire, spanner, retainer, rolling body transmitting movement successively, makes the inwall of rolling body and shell that friction and squeezing action take place, thereby makes the wheel decelerates of rotation or stop.When needing acceleration after the braking or advancing, unclamp brake lever, retainer and rolling body reset under the effect of retracing spring.This device in use when bigger than normal or less than normal as if the gap between the rolling body, rotates the square toes of axletree 1 one ends, and the gap can obtain adjusting.
The present invention has the advantage of rim brake and backpedalling brake.Compare with rim brake, because the equidirectional rotation of wheel hub retainer, so braking force is big, and cost is low, and general needs to install one on trailing wheel and get final product.The radial dimension of flywheel, brake is little, compact conformation.With the backpedalling brake ratio, its using method meets common people's custom, uses also more conveniently, owing to drive and braking force acts on Y-axis respectively and blocks, so stressing conditions is more reasonable, and structure is simpler.
