Abstract
A balance shaft support comprises a support body, a shaft hole, an installation surface and a plurality of reinforcing ribs, wherein the shaft hole is formed in the middle portion of the support body, the installation surface is arranged at the upper end of the support body, and the plurality of reinforcing ribs are arranged on the support body. The balance shaft support is characterized in that the plurality of reinforcing ribs are composed of a main reinforcing rib and a plurality of auxiliary reinforcing ribs, one end of the main reinforcing rib is connected with the upper edge of the shaft hole, the other end of the main reinforcing rib is connected with the lower portion of the installation surface, the main reinforcing rib and the shaft hole are arranged in an alignment mode, and the plurality of auxiliary reinforcing ribs are arranged on the areas on two sides of the shaft hole. The width of the main reinforcing rib is larger than or equal to the bore diameter of the shaft hole, the width of the main reinforcing rid is larger than that of each auxiliary reinforcing rib, and the main reinforcing rib is parallel to the plurality of auxiliary reinforcing ribs. The balance shaft support has the advantages that based on the fact that the self weight of the balance shaft support is improved by 0.4 kg, the stability of the balance shaft support is greatly improved, and the safety and the loading capacity of vehicles are guaranteed.
Description
Technical field
The utility model relates to a kind of heavy-duty vehicle balance shaft apparatus assembly, relates in particular to a kind of balance shaft support.
Background technology
At present, balance shaft support structure on the heavy motor vehicle comprises rack body, axis hole, attachment face and many reinforced ribs, wherein, axis hole is arranged at the rack body middle part, attachment face is arranged at the rack body upper end, many reinforced rib is arranged on the rack body, as shown in Figure 1, as can be seen from the figure, the width of many reinforced ribs is basic identical, and on rack body, evenly distribute, the balance shaft support of this structure, its design concept comes from the STER automobile suspension system of introducing from Austria the eighties in last century, when being applied on the former heavy motor vehicle, because the load carrying ability of heavy motor vehicle was relatively low at that time, this structure had both guaranteed to leave on the rack body enough lightening grooves (being the groove between the reinforced rib), had guaranteed again the structural stability of balance shaft support;
Development and progress along with society, the load carrying ability that the modern heavy-duty automobile need to be born constantly increases, the problem of bringing thus is: along with the increase of load carrying ability, be arranged between the reinforced rib of position directly over the axis hole and the attachment face and fracture often occurs, this mainly is because the load carrying ability increase causes a large amount of negative stress to concentrate on the axis hole area just above, at this moment, the setting of lightening grooves (shown in mark A among Fig. 1) in the axis hole area just above causes the size of reinforced rib relatively very thin, and structural stability herein is not enough to bear the negative stress that brings because of the load-carrying increase.
The utility model content
For the problem in the background technology, the contriver considers to cancel the lightening grooves in the axis hole area just above, and a sturdy reinforced rib is set in the axis hole area just above, solid construction body volume in the axis hole area just above is increased, thereby make it can bear larger negative stress, although this new structure can cause dead weight of vehicle to increase, but being far longer than deadweight, its effect of optimization that structural stability is brought increases the counter productive of bringing, and through experimental verification, the deadweight that increases thus only has 0.4KG, has brought constitutionally stable very big raising with minimum cost; Its concrete scheme is: a kind of balance shaft support, comprise rack body, axis hole, attachment face and many reinforced ribs, wherein, axis hole is arranged at the rack body middle part, attachment face is arranged at the rack body upper end, many reinforced rib is arranged on the rack body, and its improvement is: many reinforced ribs are comprised of a main reinforced rib and many secondary reinforced ribs; Main reinforced rib one end is connected with the axis hole upper edge, and the main reinforced rib other end is connected with the attachment face bottom, and main reinforced rib and axis hole align setting, and many secondary reinforced ribs are arranged in the zone of axis hole both sides; The width of main reinforced rib is more than or equal to the aperture of axis hole, and the width of main reinforced rib is greater than the width of secondary reinforced rib; Main reinforced rib and many secondary reinforced ribs are parallel to each other.
Useful technique effect of the present utility model is: improve the cost of 0.4KG with the balance shaft support deadweight, the stability of balance shaft support is largely increased, guaranteed safety and the load-carrying ability of vehicle.

Fig. 2, balance shaft support structural representation of the present utility model.
The specific embodiment
A kind of balance shaft support, comprise rack body 1, axis hole 2, attachment face 3 and many reinforced ribs, wherein, axis hole 2 is arranged at rack body 1 middle part, attachment face 3 is arranged at rack body 1 upper end, many reinforced rib is arranged on the rack body 1, and its improvement is: many reinforced ribs are comprised of a main reinforced rib 4 and many secondary reinforced ribs 5; Main reinforced rib 4 one ends are connected with axis hole 2 upper edges, and main reinforced rib 4 other ends are connected with attachment face 3 bottoms, and main reinforced rib 4 and axis hole 2 align setting, and many secondary reinforced ribs 5 are arranged in the zone of axis hole 2 both sides; The width of main reinforced rib 4 is more than or equal to the aperture of axis hole 2, and the width of main reinforced rib 4 is greater than the width of secondary reinforced rib 5; The secondary reinforced rib of main reinforced rib 4 and many 5 is parallel to each other.
Improvement of the present utility model, say with the most blunt words, exactly the lightening grooves directly over the axis hole 2 is removed, be integrated into a sturdy main reinforced rib 4 with originally being arranged at many reinforced ribs (many reinforced rib quantity of locating directly over the axis hole 2 shown in Fig. 1 are 2) of locating directly over the axis hole 2, the structural stability of locating directly over the axis hole 2 is strengthened.
