Technical field
The utility model relates to the balance shaft of heavy truck technology, specially refers to a kind of breakaway-element balance shaft of heavy truck assembly.
Background technology
Usually, balanced suspension for heavy-duty vehicle all is provided with a whole balance shaft that connects, and adopts the solid forging structure, and its hot and cold processing and heat treatment all need special equipment, make the processing of balance shaft of heavy truck comparatively difficult, and cost is higher.In addition, because it is the solid forging framing member, its weight is larger, does not meet the weight-saving requirement.Have again, because the prior art balance shaft of heavy truck is integral structure, if the balance shaft angle of assembling slightly has improperly during installation, very easily cause the interference of balance shaft and transmission shaft.Obviously, the prior art balance shaft of heavy truck exists that processing difficulties, cost are higher, weight is large and the problem such as installation requirement is higher.
Summary of the invention
Be the problem such as solve that processing difficulties, cost that the prior art balance shaft of heavy truck exists are higher, weight is large and installation requirement is higher, the utility model proposes a kind of breakaway-element balance shaft of heavy truck assembly.The utility model breakaway-element heavy vehicle longitudinal balance shaft assembly comprises balance shaft, balance shaft support, balance shaft housing, busbar bearing, end face bearing, locating dowel pin, balance shaft cover and bearing briquetting; Balance shaft adopts interference fit to be arranged in the centre hole on balance shaft support top; Balance shaft housing is arranged on balance shaft by busbar bearing, and is provided with locating dowel pin and end face bearing at balance shaft housing two ends, is provided with the leaf spring mounting groove on balance shaft housing top; The bearing briquetting is arranged on the balance shaft end; Balance shaft cover is arranged on the end of balance shaft housing.
Further, the utility model breakaway-element balance shaft of heavy truck assembly is provided with oil sealing in the inboard of balance shaft housing and balance shaft support junction, and arranged outside has the dust protection rubber circle.
Further, the utility model breakaway-element balance shaft of heavy truck assembly is provided with oil passage in the bottom of balance shaft housing.
Further, the balance shaft of the utility model breakaway-element balance shaft of heavy truck assembly is the blind hole hollow structure.
Further, the balance shaft support upper interior of the utility model breakaway-element balance shaft of heavy truck assembly has the reinforced rib I, and its outside also is provided with symmetrical reinforced rib II.
Further, four bights of the face of overlooking of the balance shaft housing of the utility model breakaway-element balance shaft of heavy truck assembly are provided with vertical circular port.
The useful technique effect of the utility model breakaway-element balance shaft of heavy truck assembly be simple and compact for structure, reliability is higher, weight is light and cost is lower, and processing and assembling all are easier to.
Description of drawings
Accompanying drawing 1 is the sectional structure schematic diagram of the utility model breakaway-element balance shaft of heavy truck assembly;
Accompanying drawing 4 is schematic three dimensional views that the utility model breakaway-element balance shaft of heavy truck assembly uses state.
Below in conjunction with drawings and the specific embodiments, this practical breakaway-element heavy-duty truck balancing axle assembly is further described.
The specific embodiment
accompanying drawing 1 is the sectional structure schematic diagram of the utility model breakaway-element balance shaft of heavy truck assembly, accompanying drawing 2 is the B semi-sictional view enlarged diagrams in accompanying drawing 1, accompanying drawing 3 is schematic three dimensional views of the utility model breakaway-element balance shaft of heavy truck assembly, accompanying drawing 4 is schematic three dimensional views that the utility model breakaway-element balance shaft of heavy truck assembly uses state, in figure, 1 is balance shaft, 2 is balance shaft support, 3 is balance shaft housing, 4 is busbar bearing, 5 is balance shaft cover, 6 is the bearing briquetting, 7 is oil sealing, 8 is the dust protection rubber circle, 9 is locating dowel pin, 10 is pad, 11 is the end face bearing, 201 is the reinforced rib I, 202 is the reinforced rib II.As seen from the figure, the utility model breakaway-element heavy vehicle longitudinal balance shaft comprises balance shaft 1, balance shaft support 2, balance shaft housing 3, busbar bearing 4, end face bearing 11, locating dowel pin 9, balance shaft cover 5 and bearing briquetting 6; Balance shaft 1 adopts interference fit to be arranged in the centre hole on balance shaft support 2 tops; Balance shaft housing 3 is arranged on balance shaft 1 by busbar bearing 4, and is provided with locating dowel pin 9 and end face bearing 11 at balance shaft housing 3 two ends, is provided with the leaf spring mounting groove on balance shaft housing 3 tops; Bearing briquetting 6 is arranged on balance shaft 1 end; Balance shaft cover 5 is arranged on the end of balance shaft housing 3.Adopt busbar bearing 4 to be connected between the balance shaft 1 of the utility model breakaway-element balance shaft of heavy truck assembly and balance shaft housing 3, be fixed on vehicle frame by balance shaft support 2 again, and at balance shaft housing upper mounting plate spring, be to be "off" between balance shaft housing and balance shaft, but not solid forging structure, therefore, be referred to as the disconnected balance shaft assembly.Be arranged on the bearing briquetting of the locating dowel pin at balance shaft housing two ends and end face bearing and balance shaft end, be used for preventing that balance shaft housing from skidding off from balance shaft, make balance shaft housing just be fixed on the corresponding site of balance shaft and can rotate or small sway around balance shaft, prevent the interference of balance shaft and transmission shaft, effectively reduce assembly difficulty.Rotate or flexible swinging for the accuracy and the assurance that guarantee the location, the utility model breakaway-element balance shaft of heavy truck assembly is provided with busbar bearing between balance shaft and balance shaft housing.Simultaneously, also can adjust the gap of end face bearing by increase or reduce pad between balance shaft end face and balance shaft briquetting, make it remain on better mode of operation.Be arranged on the oil sealing of balance shaft housing and inboard, balance shaft support junction, can effectively prevent oil leak.Be arranged on the dust protection rubber circle in balance shaft housing and the outside, balance shaft support junction, can effectively prevent dust upstream end spherical bearing and busbar bearing, guarantee that the rotation of bearing is worn flexibly and not.Be expendable weight, the balance shaft of the utility model heavy vehicle longitudinal disconnected balance shaft assembly is the blind hole hollow structure, and, be provided with vertical circular port in four bights of the face of overlooking of balance shaft housing.For increasing the intensity of balance shaft support, the balance shaft support upper interior of the utility model heavy vehicle longitudinal disconnected balance shaft assembly has the reinforced rib I, and its outside also is provided with symmetrical reinforced rib II, has improved reliability.Because adopting, the utility model balance shaft assembly resolves open architecture, whole balance shaft assembly comprises the parts such as balance shaft, balance shaft support, balance shaft housing, busbar bearing, end face bearing, balance shaft cover and bearing briquetting, it is comparatively easy to process, and, simple and compact for structure, productive costs is lower.
Obviously, the useful technique effect of the utility model heavy vehicle longitudinal disconnected balance shaft assembly be simple and compact for structure, reliability is higher, weight is light and cost is lower, and processing and assembling all are easier to.
