Abstract
The utility model relates to a mechanical disk clamshell brake. An installing rack part is composed of a supporting base, a sliding rack, a supporting shaft, a guide sleeve and a resetting spring; a fixed brake sheet and a movable brake sheet are opposite to a brake disk; a mechanical driving part is composed of a pull wire, an outer sleeve, a driving shaft, a shaft coupling, a screw rod and a spline guiding sleeve. The pull wire controlled by hands can drive the driving shaft and the screw rod to rotate, the rotation of the driving shaft and the screw rod is converted into an axial movement through the spline guiding sleeve, and the movable brake sheet is closed to the brake disk, and furthermore, the sliding rack is slid to move, so that the two brake sheets clamp the brake disk. The utility model has the advantages of simple structure, large braking moment and reliable function.
Description
The utility model belongs to a kind of parts on the traveling vehicle, and it relates to a kind of structure of New Brake.
The deceleration and stopping performance of bicycle and motor bike is aspect very important one in safety rate, popular drg is the hydraulic pressure fixed caliper disc on the Guo Ji motor bike now, be two brake facings to be pressed on hard-wired brake disc on the wheel shaft with hydrostatic drive, it has advantages such as lock torque is big, reliable, stable, but it is very tight that the hydraulic efficiency pressure system accuracy of manufacture requires, cost height and maintenance difficult; What use always on bicycle is trolley type or pincers wheel brake, it has simple in structure, the low characteristics of cost, but this brake is all unreliable after the wheel distortion, the production development and the retrofit of bicycle and middle-size and small-size motor bike are all very fast at present, desire adopts caliper disk brake, but is subjected to the restriction of technological level and cost to bring very big difficulty.
The purpose of this utility model provides a kind of mechanically operated caliper disk brake, and it has dependable performance and the low characteristics of cost simple in structure.
By as above design, the drg of the mechanical jaw disc type that this programme provided includes brake disc (1), brake facing, erecting frame, and running part, its concrete feature is: its erecting frame includes bearing (4) sliding rack (2) pivot shaft (10), guide pillar (12), retracing spring (11), its bearing is installed on the vehicle body, sliding rack connects with bearing by pivot shaft and guide pillar, between sliding rack inside and guide pillar, retracing spring is housed, the space breach that brake facing is installed is arranged at the bottom of sliding rack, side at breach has a splined hole, its brake facing includes fixedly brake facing (3B) and movable brake facing (3A), fixedly brake facing is fixed on the left side of sliding rack space, movable brake facing is mounted in an end of the spline guide pillar (13) that has internal whorl, two brake facings and be installed between the brake disc on the wheel axle head uniform endplay is arranged, its running part comprises the backguy (5) that has overcoat (14), the transmission shaft (6) of band lever, the coupler of angle adjustable (7), can limit the leading screw (9) of axial location, the overcoat of its hand operation backguy is fixed on the bearing, pull wire head connects with the lever head of transmission shaft, and the screw thread of its leading screw matches with the inner hole thread of spline guide pin bushing.
Making bearing and the joining pivot shaft of sliding rack and guide pillar in this programme erecting frame part can be the form of single square shaft, also can be the form of the circular shaft of double joint.The coupler of the angle adjustable of its running part is a cover that has splined hole, and the axle head of its transmission shaft is a castellated shaft.
Adopt this programme can embody following preceence: 1. this programme has been realized the structure of caliper disk brake, but has replaced hydraulicdriven form with the form of machinery, simplifies the structure, reduced cost; 2. caliper disk brake hygrometric state deceleration and stopping performance is good, and the brake facing gap is little, and the side that brake disc is vertical is difficult for the pickup dirt, has the dirt on the go also easily to remove, and lock torque is all big than belt, shoe brake; 3. the performance of drg is insensitive to the distortion of wheel, to not abrasion of rim, can remove the wear-resisting requirement of rim decorative cover from; 4. be easy to make and promote the use of, create conditions for opening up new model.
Fig. 1 is the structural representation of this programme mechanical jaw disc type brake.
Structure and principle of work below in conjunction with description of drawings this programme embodiment.Brake disc (1) is to be fixedly connected on the end face of wheel axle sleeve, should guarantee squareness with axis, two brake facings (3A) and (3B) be contained in the left surface of spline guide pin bushing (13) and sliding rack (2) space respectively, the spline guide pin bushing is installed in the splined hole of sliding rack, sliding rack (2) links with bearing (4) by pivot shaft (10) and guide pillar (12), bearing (4) is installed on the vehicle body, and is even by the adjustment assurance brake facing and the gap between the brake disc of installation site.The overcoat (14) of the backguy of hand operation brake lever (5) is fixed on the bearing (4), backguy connects with the lever end of transmission shaft (6), transmission shaft (6) connects with the leading screw that can limit axial location (9) by the drive coupling (7) of angle adjustable, and leading screw (9) matches with spline guide pin bushing (13).Applying the handbrake during use just spurred backguy (5), the lever of pulling transmission shaft rotates transmission shaft (6), the rotation of leading screw (9) produces spline guide pin bushing (13) and moves axially, make 3A push brake disc (1) to, being close to moving axially of back spline guide pin bushing then makes sliding rack move to right, make fixedly brake facing also press to brake disc, two brake facings are with the tight lock torque that produces of brake disc pincers, the interior retracing spring of sliding rack this moment is compressed, when decontroling rim brake sliding rack is retreated, brake facing (3A) is retreated.
Brake disc diameter ∮ 160 in this programme, thickness 3.5mm, hand brake power is 180N, the brake power square of drg is 167.33Nm, is 5760N to the resultant action pressure of brake disc.See that from above data it is a kind of more common superior pattern of several brake performances really.This preproduction is through stable performance on probation, reliable in action.
