Abstract
The utility model relates to a balancing type parking and emergency braking device. The lower part of an inner tension rod which is sheathed with a spring and is arranged in an operating lever 7 is provided with a circular plug-shaped ratchet pawl 8, and a fan-shaped arc side of a locking plate 10 is provided with a ratchet. An upper supporting rack 17 of a cross beam of a motorcar is connected with one end of an energizing arm 12, the other end of the energizing arm 12 is connected with a main steel cable 3, and the middle part near by one side is connected with one end of an adjustable tension rod 13. In addition, the other end of the adjustable tension rod 13 is connected with a balance bar 20. The utility model has the advantages of simple structure, low cost, less difficulty and working capacity of maintenance and correction, capability od quick and repeated use for many times, capability of automatic regulating the braking ability of a left and a right wheels, low failure, difficult failure, etc. Moreover, the balancing type parking and emergency braking device can be widely used on home-made large-sized passenger cars and motor trucks.
Description
The utility model relates to a kind of Parking, emergency brake device of full-sized car, especially bogie type Parking, emergency brake device.
Homemade high capacity waggon, central authorities' (hand) drgs that are positioned at the change-speed box rear portion that adopt are realized braking during standstill more.When need were implemented Parking or emergency brake, chaufeur pulling handle made central Parking Brake produce braking, and the motional inertia of vehicle or potential energy are imposed restrictions on by main reduction gear, transmission shaft, thereby reached its braking purpose.Its deficiency is:
1, during the leakage of oil of change-speed box Rear oil seal, central hand brake is easy to lose efficacy.
2, maintenance, adjustment are numerous and diverse, and are difficult for keeping its regular good technique situation.
When doing emergency brake with central hand brake during 3, vehicle is advanced, transmission system will bear powerful impact load (particularly descending) and easily cause pernicious machine to undermine accident.Therefore " central authorities emergency brake in hand braking should not advancing as vehicle " have become expert's common recognition.Certainly also be difficult to satisfy the basic demand of 6.1.2 bar " automobile should have the emergency brake function " among the GB7258-1997 (self-propelled vehicle safe in operation engineering factor).
In addition, there was the homemade large-scale passenger and freight car of minority to begin to adopt spring energy-storage Parking, emergency brake device in recent years.Though this device has overcome central hand braking shortcoming, and also improvement greatly of deceleration and stopping performance, complex structure, the cost height, maintenance difficulty and work capacity strengthen, and can not be repeatedly used when full car air pressure is not enough.And in easily " traffic congestion " in case traffic environment in service brake fault or full car air pressure forfeiture and spring energy-storage is braked when coming into force, drag can not, brake off is not can finish in a moment yet, " traffic congestion " more very.
Disclosing " a kind of Parking with trammel beam, emergency brake device " at number of patent application 97207477.5 is for city bus designs, so exist the brake air chamber is had bigger change and handles weak points such as backhaul is big.
The purpose of this utility model is on the basis of not changing former car layout and parts, the deficiency that prior art is existed is further overcome, thereby provides a kind of simple in structure, cheap, maintenance adjustment difficulty and work capacity is little, good bogie type Parking, the emergency brake device of Parking, emergency brake usefulness that can automatically regulating left and right wheels system usefulness.
Above-mentioned purpose of the present utility model is to realize like this, include pulley, sheave shaft, main cable, joystick, the joystick bearing pin, the pull bar bearing pin, trammel beam, divide drag-line, braking adjusting arm, the service brake air chamber, brake camshaft, brake wheel, the brake shoe brake cheek return spring, friction lining, brake shoe brake cheek fixed end pin, brake shoe brake cheek, draw-in bar upper end in its joystick links to each other with the releasing handle, there is circular stopper ratchet the lower end that is with spring, the joystick lower end is connected with fan-shaped locking plate by the joystick bearing pin, locking plate is the fan-shaped arc limit ratchet, the vehicle beam upper bracket links by reinforcement arm axle and force increasing arm one end, the other end of force increasing arm and main cable and returning pull-spring link, the middle part is connected with adjustable rod one end that has setting nut by the middle pin of living partially on one side, and the lining that adjustable rod passes on the vehicle beam is connected with trammel beam.
When using the utility model to implement Parking or emergency brake, chaufeur pulling joystick, make force increasing arm deflection forward by main cable, and driving adjustable rod and trammel beam reach, the branch drag-line that is sub-packed in the trammel beam two ends then spurs former car braking adjusting arm makes the brake shoe expander rotation open brake shoe brake cheek and produce brake action.If between left and right wheels brake shoe brake cheek, the drum crack have different, trammel beam promptly according to left and right sides force difference and automatically angle of deflection realize automatically regulating, with the harmony of braking about realizing.Therefore, when emergent system, wheel breaks away because of the unlikely generation of the equilibrium of both sides brake efficiency, has improved the safety of vehicle under emergency rating.When hand of driver behind joystick, be installed on plug formula ratchet in the joystick at spring pressure and locking plate locking, maintenance car brakeing state.When the need brake off, chaufeur press remove handle and before push away joystick, braking promptly is disengaged.
The utility model compared with prior art, have cheap, maintenance adjustment difficulty simple in structure and work capacity is few, can be repeatedly fast repeated usage, can automatically regulating left and right wheels brake efficiency, when emergency brake, do not have impact load, mechanism is soft, passenger's collision case in the time of can reducing emergency brake, and have the low characteristics such as inefficacy that are difficult for of fault rate.Can extensively should be in homemade large-scale visitor, lorry.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
