Abstract
The invention discloses a sedan handbrake transmission mechanism. The sedan handbrake transmission mechanism comprises a bracket (1), a handle (2) and a brake pulling cable, wherein the handle (2) is hinged at the upper end of the front part of the bracket (1); the brake pulling cable consists of a front pulling cable (4) and a rear pulling cable (5); the upper end of the front pulling cable (4) is connected with the handle (2), and the lower end of the front pulling cable (4) is hinged with the front end of the lower part of a conversion block (3); the top of the conversion block (3) is hinged with the lower end of the middle of the bracket (1); and the rear end of the lower part of the conversion block (3) is hinged with the front end of the rear pulling cable (5). By the high-efficiency continuous transmission of the front pulling cable and the rear pulling cable of the brake pulling cable, the transmission efficiency of a handbrake is improved. According to the change of the angle and the side length of a triangular block, the transmission ratio of a handbrake mechanism can be changed. Therefore, a transmission ratio regulating mode is added, the transmission ratio is large in regulation range and flexible in regulation, and the defect of regulation of the transmission ratio according to the length of the handle is overcome.
Description
Technical field
The invention belongs to automobile technical field, specifically, particularly a kind of car manual braking drive mechanism.
Background technology
The car manual braking mechanism is mainly used in the M/C of car and stays moving.Existing car manual braking mechanism mainly comprises support, the brake line that is hinged on the handle on support and is connected with handle.Turning handle backward during work, handle pulls forward brake line, carries out brake and stays moving.The deficiency of existing structure is:
1) front end of brake line directly is connected with the bottom of handle, can only regulate transmitting ratio by the length of handle like this, and when brake system needed larger transmitting ratio, the parking brake handle can be very long, affects human engineering, interferes with and select gear shift;
2) brake line is front high rear low, and the brake line loading angle is larger, makes the driving efficiency of whole braking mechanism low.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of transmitting ratio the easy to adjust and high car manual braking drive mechanism of driving efficiency.
Technical scheme of the present invention is as follows: a kind of car manual braking drive mechanism, comprise support (1), handle (2) and brake line, at the anterior upper end hinged handle (2) of support (1), described brake line is comprised of fore stay (4) and back stay (5), the upper end of fore stay (4) is connected with handle (2), the front end of the lower end of fore stay (4) and conversion block (3) bottom is hinged, the lower end at the top of described conversion block (3) and support (1) middle part is hinged, and the rear end of conversion block (3) bottom and the front end of back stay (5) are hinged.
The present invention is divided into two sections of fore stay and back stays with brake line, and is connected by conversion block between fore stay and back stay.During work, staff is pulled handle, and handle will drive fore stay and up draw, and fore stay drives conversion block around the hinge-point rotation of conversion block and support, drives back stay by conversion block again and moves forward, to complete the hand-operated brake operation.
Because brake line has been divided into fore stay and back stay, fore stay driving handle and conversion block, its driving efficiency is high, back stay is by the conversion block transmission, and it tilts forward and back angle and diminishes, driving efficiency is high, has become high efficiency fore stay and the continuous transmission of back stay so be equivalent to brake line mechanism by a brake line transmission of low efficiency before, thereby has improved the transmitting ratio of handbrake mechanism.Simultaneously, because the size shape of conversion block can change as required, so, the position of conversion block and support, fore stay and three hinge-points of back stay also can arbitrarily change, and by the relative distance of three hinge-points and each other the variation of angle can change the transmitting ratio of parking brake.Therefore, the present invention has not only increased a kind of regulative mode of transmitting ratio, and its setting range is large, and flexible adjustment has avoided regulating by decreased food the deficiency of transmitting ratio.
Described conversion block (3) is comprised of symmetrical a pair of corner block (6), this is to the both sides of corner block (6) separation in support (1), and the top corner part of corner block (6) is hinged by rivet and support (1), the front base angle of corner block (6) and fore stay (4) are hinged, and the rear base angle of corner block (6) and back stay (5) are hinged.Because the position line of three hinge-points of conversion block and support, fore stay and back stay also consists of a triangle, thus conversion block is designed to corner block shape, and arrange that at the place, three angles of conversion block hinge-point meets the transmission requirement.Simultaneously, the non-deformability of corner block is strong, and conversion block is comprised of symmetrical a pair of corner block, can further improve the intensity of conversion block.
Described corner block (6) is formed with the reinforced rib of evagination by punch forming at the integral middle of corner block (6).The integral middle of corner block is formed with the reinforced rib of evagination, can improve the anti-twist deformability of corner block.And corner block is by punch forming, and technique is simple, and speed is fast, and intensity is high.
Produce friction between its upper edge and support when preventing that corner block from rotating, the upper edge of described corner block (6) is bent to form flange outward.
Beneficial effect of the present invention is as follows:
1) brake line mechanism is become high efficiency fore stay and the continuous transmission of back stay by a brake line transmission of low efficiency before, improved the driving efficiency of parking brake.
2) can change the transmitting ratio of handbrake mechanism by the variation of corner block angle and the length of side, so not only increased a kind of regulative mode of transmitting ratio, and its setting range be large, flexible adjustment has avoided regulating by decreased food the deficiency of transmitting ratio.
