Abstract
An expander assembly of an automotive brake comprises a shell (1) of an expander, a piston rod (2) is arranged on the left side of the shell (1), a supporting seat (3) is arranged outside the piston rod (2), a piston bush (4) is arranged on the right side of the shell (1), an adjusting sleeve (5) is arranged in the piston bush (4), an adjusting bolt (6) is screwed in the adjusting sleeve (5), a clamping seat (7) is arranged at the outer end of the adjusting bolt (6), inclined planes (8) with the inclination of 1:16 are arranged on inner end faces of the piston rod (2) and the piston bush (4), a guide groove is arranged on each inclined plane (8), a wedge assembly (9) is vertically arranged on the upper portion of the shell (1), and sliders (10) matching with the guide grooves of the inclined planes (8) are arranged at the lower end of the wedge assembly (9). By linear movement, a wedge passing through the 1:16 inclined planes is enlarged by 16 times. Safety coefficient is increased. The expander assembly of the automotive brake is small in size, compact in structure and high in adaptability by matching with an ABS (anti-locking braking system). Imported products are substituted completely, unit cost is reduced by more than 2000 RMB, and the expander assembly of the automotive brake is an ideal product of a truck braking system.
Description
Technical field
The utility model relates to the key components and parts of automotive brake, specifically is the expander assembly of automotive brake.
Background technique
The original braking of automotive brake belongs to non-equilibrium braking; The tension of hoof is inconsistent about being embodied in, and makes the brake block degree of wear inconsistent, makes left and right sides brake weight inconsistent; Cause Braking efficiency to reduce, brake is prone to weak on the abrupt slope; The unreasonable structure that makes faults such as related components (breaking phenomenons such as hub bearing is loosening, axle tube bending break like brake drum) loosening wearing and tearing of appearance and damage, its basic reason belong to non-equilibrium break self causes.Specifically be system of connections, thereby cause the inefficacy of non-equilibrium braking, make whole brake system failure, influence the performance of car load, more likely cause the phenomenon of car crash owing to a series of complicacies such as the required adjustment arms of break.
Summary of the invention
The purpose of the utility model is in order to improve the performance of whole braking system, the special expander assembly that proposes automotive brake.
The technological scheme of the utility model does for this reason, and the expander assembly of automotive brake comprises it is characterized in that the housing (1) of expander: be provided with piston column (2) in the left side of housing (1), the outer bearing (3) that is provided with of piston column (2); The right side of housing (1) is provided with piston sleeve (4), is provided with adjustment cover (5) in the piston sleeve (4), is rotary with adjustment bolt (6) in the adjustment cover (5), and the outer end of adjustment bolt (6) is provided with deck (7); Wherein the interior edge face of piston column (2) and piston sleeve (4) is provided with inclined-plane (8), and inclined-plane (8) are provided with guiding groove; Be provided with voussoir assembly (9) from the upper vertical of housing (1), the sliding device (10) that the lower end of voussoir assembly (9) is provided with and the guiding groove of inclined-plane (8) cooperates.
Improvement to such scheme is: the gradient of said inclined-plane (8) is 1:16, and same, the gradient of guiding groove also is 1:16.
Improvement to such scheme is: described adjustment cover (5) is divided into two joints, meshes together through unidirectional teeth between two joints.
Beneficial effect:
The utility model has been cancelled original balancing brake system, adopts the straight line motion of pneumatic element directly to drive the motion of voussoir assembly; The effective braking distance that inclined-plane through 1:16 makes it is also with the amplification of 1:16; Adjustment cover is divided into two joints and the engagement through unidirectional teeth makes its adjustment improve safety coefficient effectively to a direction motion.
The utility model and abs braking system mate, and have characteristics such as volume is little, compact structure adaptability is strong; Simultaneously the expanding brake assembly is when the speed of a motor vehicle is too fast on the abrupt slope, and its braking force increases thereupon, the speed of a motor vehicle is stabilized in has certain retarded acting in certain scope; Substituted imported product fully, after realizing domesticizing, single buying reduces cost and reaches two over thousands of yuan, is the ideal product of truck braking system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is housing among the figure, 2 piston columns, 3 bearings, 4 piston sleeves, 5 adjustment covers, 6 adjustment bolts, 7 decks, inclined-plane 8,9 voussoir assemblies, 10 sliding devices.
Embodiment
The utility model is as shown in Figure 1.
The expander assembly of automotive brake comprises the housing 1 of expander being provided with piston column 2 in the left side of housing 1, the piston column 2 outer bearings 3 that are provided with; The right side of housing 1 is provided with piston sleeve 4, is provided with adjustment cover 5 in the piston sleeve 4, is rotary with adjustment bolt 6 in the adjustment cover 5, and the outer end of adjustment bolt 6 is provided with deck 7; Wherein the interior edge face of piston column 2 and piston sleeve 4 is provided with inclined-plane 8, and inclined-plane 8 is provided with guiding groove; Be provided with voussoir assembly 9 from the upper vertical of housing 1, the lower end of voussoir assembly 9 is provided with the sliding device 10 that cooperates with the guiding groove on inclined-plane 8.
The gradient on inclined-plane 8 is 1:16, and same, the gradient of guiding groove also is 1:16.
Adjustment cover 5 is divided into two joints, meshes together through unidirectional teeth between two joints.
Claims (3)
1. the expander assembly of automotive brake comprises it is characterized in that the housing (1) of expander: be provided with piston column (2) in the left side of housing (1), the outer bearing (3) that is provided with of piston column (2); The right side of housing (1) is provided with piston sleeve (4), is provided with adjustment cover (5) in the piston sleeve (4), is rotary with adjustment bolt (6) in the adjustment cover (5), and the outer end of adjustment bolt (6) is provided with deck (7); Wherein the interior edge face of piston column (2) and piston sleeve (4) is provided with inclined-plane (8), and inclined-plane (8) are provided with guiding groove; Be provided with voussoir assembly (9) from the upper vertical of housing (1), the sliding device (10) that the lower end of voussoir assembly (9) is provided with and the guiding groove of inclined-plane (8) cooperates.
