Utility model content
For the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, lightweight battery-driven car subframe.
Battery-driven car subframe, comprise U-shaped Guan Liang (2), the leg end outside, the left side of U-shaped Guan Liang (2) is fixed with left vehicle body mounting bracket (1), the leg end outside, the right of U-shaped Guan Liang (2) is fixed with right vehicle body mounting bracket (6), the outside of U-shaped Guan Liang (2) two leg bottoms is fixed with respectively left front swing arm mounting bracket (3) and right front swing arm mounting bracket (5), and U-shaped Guan Liang (2) fixes two deflector mount pads (4) in bottom; Subframe both sides are about middle symmetrical.
For guaranteeing the structural strength of subframe, the antitorque Combination property of bending resistance that effectively strengthens subframe, improves vehicle security, except subframe pipe beam material adopts solid drawn pipe Φ 45 × 3mm, all the other materials all adopt automobile high-strength plate, and the material thickness of selection is 2.5mm.
Left vehicle body mounting bracket (1) has two mounting holes: mounting hole a and mounting hole b; Right vehicle body mounting bracket (6) has two mounting holes: mounting hole c and mounting hole d.
Preferably, mounting hole between left vehicle body mounting bracket (1) and right vehicle body mounting bracket (6) is apart from as follows: ac pitch-row is 884 ± 1.5mm, and bd pitch-row is 873.5 ± 1.5mm, has guaranteed in the Y direction and the coordinating of vehicle body.Left vehicle body mounting bracket (1) ab pitch-row is 57.9 ± 0.2mm, and right vehicle body mounting bracket (6) cd pitch-row is 58.7 ± 0.2mm, has guaranteed in XY plane and the coordinating of vehicle body.Left front swing arm mounting bracket (3) and right front swing arm mounting bracket (5) pitch-row 723.8 ± 1.5mm guaranteed and being connected of front swing arm in the Y direction, thereby limited the reasonableness of four wheel locating parameter.Two deflector mount pads (4) pitch-row is 236.6 ± 1.5mm, in the Y direction with the reasonable coordination of deflector band tie rod assembly.
For proof strength, left and right front swing arm mounting bracket (3,5) section is " several " font, and deflector mount pad (4) section becomes " V " font, is transformed into smooth end face by falling the wedge angle of " V " font end face.
Compared with existing subframe, the utility model adopts solid drawn pipe and panel beating support welding to realize subframe functional requirement, and weight is slim and graceful.Production and processing and quality control, about middle symmetrical, simple in structure, are convenient in subframe both sides.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model plan structure schematic diagram;
Fig. 3 is A-A section-drawing in Fig. 1;
Fig. 4 is B-B section-drawing in Fig. 2.
The specific embodiment
As shown in Figure 1 and Figure 2.Battery-driven car subframe comprises U-shaped pipe beam 2, the leg end outside, the left side of U-shaped pipe beam 2 is fixed with left vehicle body mounting bracket 1, the leg end outside, the right of U-shaped pipe beam 2 is fixed with right vehicle body mounting bracket 6, the outside of 2 liang of leg bottoms of U-shaped pipe beam is fixed with respectively left front swing arm mounting bracket 3 and right front swing arm mounting bracket 5, and two deflector mount pads 4 are fixed in U-shaped pipe beam 2 bottoms; Subframe both sides are about middle symmetrical.
The U-shaped pipe beam 2 of subframe passes through tool locating weld together with other part.When use, be bolted with vehicle body by left vehicle body mounting bracket 1, right vehicle body mounting bracket 6; Left front swing arm mounting bracket 3, right front swing arm mounting bracket 5 are bolted with front swing arm; Deflector mount pad 4 is bolted with deflector band tie rod assembly.
