Abstract
The utility model relates to a vehicle tail girder steel rubber barb emergency brake device which comprises a brake piece, a fixed rod, a drive rod and a drive mechanism. The brake piece is composed of an upper layer and a lower layer, the upper layer is a steel layer, the lower layer is a rubber layer, the lower surface of the rubber layer is wave-shaped, two ends of the fixed rod are respectively and fixedly connected with the steel layer and a vehicle tail girder, and the drive rod is formed by a driving rod and a driven rod in a hinged mode. One end of the driving rod is hinged on the vehicle tail girder, one end of the driven rod is fixed on the fixed rod, and the drive mechanism is arranged on a vehicle body and drives the driving rod to rotate along a hinge shaft of the vehicle tail girder. With the structure, when the emergency brake device is not used, the brake piece is suspended between the bottom portion of the vehicle tail and the ground, and normal driving is not influenced. When brake fails, the drive mechanism is started to drive the driving rod to rotate along the hinge shaft of the vehicle tail girder to put the brake piece down, and the lower surface of the rubber layer is tightly contacted with the ground so as to greatly increase abrasion force and enable a vehicle to be rapidly stopped so as to prevent an accident from happening.
Description
Technical field
The utility model relates to the vehicle technology field, is a kind of tailstock beam steel rubber hangnail emergency brake specifically.
Background technology
Along with The development in society and economy, the important vehicle that automobile has become people's production and transport and ridden instead of walk, various model automobiles are more and more, dead-weight capacity is increasing, vehicle speed is also more and more faster, thereupon and extremely be the rising of auto against traffic accident, pernicious frequent accidents takes place, and has brought massive losses for people's lives and properties.Wherein, brake failure is the major reason that traffic accident takes place, though all can dispose brake gear on the automobile, common brake gear has " drum brakes " and " disk type brake " two kinds, but the situation of brake failure always is difficult to avoid, major cause has: 1, brake system is lacked necessary maintenance, impurity is too many, poorly sealed in the master cylinder, vacuum booster pump lost efficacy, brake solution is crossed and vapour lock, master cylinder or wheel cylinder leakage of oil, storage tank or pipe interface gas leakage are occurred after dirty or several brake solution mixing uses are heated; 2, misoperation causes engine failure, makes brake facing frictional heat, brake hubs charing, brake function entirely ineffective as long-time descending; 3, serious overload under the effect of acceleration due to gravity, has strengthened vehicle movement inertia, directly causes brake failure.Under the situation of brake failure, chaufeur cannot be taked other expeditious measures at all, can only cause the generation of tragedy.
The utility model content
In order to overcome the defective of above-mentioned prior art, technical problem to be solved in the utility model provides a kind of tailstock beam steel rubber hangnail emergency brake, and it can play the emergency brake effect when vehicle brake is malfunctioning, the generation that effectively tries to forestall traffic accidents.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of tailstock beam steel rubber hangnail emergency brake, it is installed on the tailstock crossbeam, comprise brake facing, fixed link, drive spindle and driver train, described brake facing is by two-layer composition up and down, the upper strata is the steel layer, lower floor is rubber layer, the lower surface of described rubber layer is wavy, captive joint with tailstock crossbeam with the steel layer respectively in the two ends of described fixed link, described drive spindle is by driving lever and follower lever is hinged forms, one end of described driving lever is hinged on the tailstock crossbeam, one end of described follower lever is fixed on the described fixed link, the other end of described driving lever and the other end of follower lever are hinged, and described driver train is arranged on the car body and drives described driving lever and rotates along the jointed shaft with tailstock crossbeam.
Wherein, the length of described brake facing is 1/3 ~ 2/3 of back wheels of vehicle spacing.
Wherein, the width of described brake facing is 1/3 ~ 2/3 of brake facing length.
Wherein, the thickness of described rubber layer is 20 ~ 30mm.
Tailstock beam steel rubber hangnail emergency brake provided by the utility model, driving lever and follower lever are not on the same straight line when not using, brake facing is suspended between tailstock bottom and the ground and can influence normal driving, when brake failure, chaufeur can pass through the emergency start driver train, drive described driving lever along and the jointed shaft of tailstock crossbeam rotate and gradually and form a straight line between the follower lever, thereby putting down brake facing makes the lower surface of rubber layer closely contact with ground, increased friction force greatly, vehicle is stopped, the generation that avoids traffic accident in short time and short range.
Description of drawings
Figure 1 shows that the structural representation of the utility model embodiment.
Label declaration:
1, tailstock crossbeam; 2, brake facing; 3, fixed link; 4, drive spindle;
20, steel layer; 21, rubber layer; 40, driving lever; 41, follower lever.
The specific embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also shown in Figure 1, the tailstock beam steel rubber hangnail emergency brake of present embodiment, it is installed on the tailstock crossbeam 1, comprise brake facing 2, fixed link 3, drive spindle 4 and driver train, described brake facing 2 is by two-layer composition up and down, the upper strata is steel layer 20, lower floor is rubber layer 21, the lower surface of described rubber layer 21 is wavy, captive joint with tailstock crossbeam 1 with steel layer 20 respectively in the two ends of described fixed link 3, described drive spindle 4 is by driving lever 40 and follower lever 41 hinged forming, one end of described driving lever 40 is hinged on the tailstock crossbeam 1, one end of described follower lever 41 is fixed on the described fixed link 3, and the other end of the other end of described driving lever 40 and follower lever 41 is hinged, and described driver train is arranged on the car body and drives described driving lever 40 and rotates along the jointed shaft with tailstock crossbeam 1.
Adopt the tailstock beam steel rubber hangnail emergency brake of said structure, driving lever 40 is not on the same straight line with follower lever 41 when not using, brake facing 2 is suspended between tailstock bottom and the ground and can influence normal driving, when brake failure, chaufeur can pass through the emergency start driver train, drive described driving lever 40 along and the jointed shaft of tailstock crossbeam 1 rotate and gradually and form a straight line between the follower lever 41, thereby putting down brake facing 2 makes the lower surface of rubber layer 21 closely contact with ground, increased friction force greatly, vehicle is stopped, the generation that avoids traffic accident in short time and short range.
