Abstract
The utility model relates to a kind of high power density front suspension, form subframe by side arm (3), after-frame (1) and bogie side frame (2), on bogie side frame (2), connect respectively swing arm (9), stabilizer rod (4), swing arm one end connects steering swivel (5), and the upper steering track rod (6) that connects of side arm (3) is connected with steering swivel (5).Wherein swing arm (9) is L-type structure, and one end is provided with ball pin seat (7) and is welded to connect with swing arm, and ball pin seat is pressed with rubber bush in (7), and the other end is connected with horizontal bearing pin (10) and is connected in the side of bogie side frame (2).Compare with traditional press-fiting with riveting method, the utility model has the advantage of, be easy to control ball pin assembly spatial attitude; Precision to mount pad is lower; The pull-out force of welded connection type ball pin in meeting the staring torque of ball pin and moment of rotation and requiring has significantly improved 10% left and right.
Description
Technical field:
The utility model relates to auto parts and components, particularly a kind of high power density front suspension.
Background technology:
Manufacturing and designing of front suspension is to meet under the strength conditions of each parts, assembly, pass through optimal design, the cover rigidity of appropriate design rubber lining, the stressing conditions of the each element of reasonable layout suspension, realize the balance of road-holding property and riding comfort, and structure by the each parts of appropriate design is convenient to be manufactured, processing and assembling, and the requirement of automobile lightweight, low fuel oil consumption, automobile is being done to important effect aspect fuel economy, road-holding property and traveling comfort.Existing front suspension is mainly made up of subframe welding assembly, swing arm, lining etc., but unreasonable as swing arm, bushing design of some parts wherein caused the defects such as front suspension structure complexity, less stable.
Summary of the invention
The purpose of this utility model is exactly the defect existing in order to overcome prior art, a kind of high power density front suspension providing.
The utility model has adopted following technical scheme:
A kind of high power density front suspension, comprise the subframe being formed by the bogie side frame of side arm, after-frame and both sides, on the bogie side frame at side arm two ends, connect respectively swing arm and stabilizer rod, on side arm, connect steering track rod, swing arm one end connects steering swivel, steering track rod is connected cooperation with steering swivel, it is characterized in that: swing arm is L-type structure, the one end on its L limit is provided with ball pin seat and swing arm is welded to connect, the other end is provided with horizontal bearing pin, the two ends of horizontal bearing pin are respectively equipped with mounting hole, and this mounting hole is bolted in the screw of the side of bogie side frame.
On the basis of technique scheme, there is following further technical scheme:
Above the bogie side frame on every limit, connect respectively a permanent seat, be provided with a fixed block in permanent seat, be provided with the fixed orifice being connected with stabilizer rod in fixed block, fixed block one side is provided with opening and is communicated with fixed orifice.
The two ends of horizontal bearing pin are respectively equipped with chamfered edge spindle nose, and mounting hole is located at chamfered edge spindle nose middle part.
Owing to having adopted technique scheme, the design of L-type swing arm has improved the ride comfort of running car, and ball pin seat and swing arm are welded to connect the obvious pull-out force that improves ball pin, and equipment investment is little, and product weight is light, and price is low;
Between ball pin seat and swing arm mount pad, adopt that to be welded to connect be a large feature of swing arm design: swing arm and ball pin are put into swing arm by free-running fit and welded the swing arm hole of assembly and be welded to connect, press-fit and riveted joint has following some advantage with traditional: 1.. be easy to control ball pin assembly spatial attitude; 2.. the precision to mount pad is relatively low, and equipment investment is little, product price is low; 3.. existing with press-fiting or riveted type ball pin, the pull-out force of welded connection type ball pin in meeting the staring torque of ball pin and moment of rotation requirement has significantly improved 10% left and right.
Being connected between stabilizer rod and subframe adopted the connection mode of permanent seat and fixed block, avoid originally directly nut being welded to (position degree to nut is had relatively high expectations), simplify welding sequence, reduced the input cost of equipment, and efficiency of assembling has been high.
